Coleman hatchery will free 180,000 tiny salmon in survival experiment
Will hatchery-raised salmon have a better chance of surviving their journey to the Pacific Ocean and back if they get a 75-mile head start? That’s the question a three-year study hopes to answer for the U.S. Fish and Wildlife Service and four partner organizations. The plan Saturday is to release 180,000 salmon fry into the Sacramento River 75 miles downriver from the Coleman National Fish Hatchery.
